OPERATION

7.2 PROBE CONNECTION

 The sound velocity in liquids like oil, and solids like the calibration block, depends on temperature. 

For this reason, a correct measurement requires a previous temperature measurement for the test object. The results must be 
compared with the corresponding table.

7.1 COUPLANT

The instrument is designed for use with brake paste Mercedes-Benz “Bremspaste bräunlich”, A002 989 37 51.

 Couplant must be ordered separately. The coupling agent used has an influence on the proper functio-

ning of the device. Choose a coupling agent with non-corrosive properties so as not to damage the probe. Always pay attention to 
the safety instructions given in the safety data sheet.

 Accessories for temperature measurement are not included in the delivery. 

Nominal values with respect to temperature are supplied by the manufacturer of the workshop diagnosis equipment. 
Inappropriate temperature determination and / or an incorrect correction value table can lead to incorrect measurements and 

the resulting consequential damage.

ACS is not liable for any damage or loss (whether contractually or unauthorized, including negligence) caused by not following 

this warning.

1. First connect the LEMO cable to the measuring device, by inserting the plug of the cable into the socket. The plug at 

either end of the cable is identical.

2. Repeat the connecting procedure for the probe.

 Pay attention to ease of movement when making 

the plug connection. Before making the connection, there must be no dirt or 
foreign objects in the sockets.

3. When separating the cable from device or probe, carefully grasp the 

LEMO plug by the knurled sleeve and straightly draw it back.
